  • Patent number: 11442566
    Abstract: A display panel and a display device are provided. The display panel includes a touch unit. The touch unit includes first detection electrode groups arranged along a first direction, second detection electrode groups arranged along a second direction, and bridges including a first bridge. The first direction intersects the second direction. Each of the plurality of first detection electrode groups includes a first detection electrode sub-block and a second detection electrode sub-block that are adjacent to each other along the first direction. The first detection electrode sub-block includes a first main portion, and the second detection electrode sub-block includes a second main portion and a first branching portion. The first branching portion extends toward the first main portion, and the first bridge is configured to electrically connect the first branching portion and the first main portion.

  • Publication number: 20220255037
    Abstract: A display panel with a display region and a non-display region includes a base substrate; a device layer, disposed on one side of the base substrate, covering the display region, and including a cathode layer; and an encapsulation part, arranged around the device layer in the non-display region and including a metal pad layer surrounding the cathode layer. The metal pad layer and the cathode layer are separated by a gap. The cathode layer has a first irregularly-shaped edge, including first deformed portions and second deformed portions that are alternately distributed. Each first deformed portion extends convexly in a direction toward the metal pad layer, and each second deformed portion extends concavely in a direction away from the metal pad layer. In an extending direction of the first irregularly-shaped edge, a length of the first deformed portion is less than or equal to a length of the second deformed portion.

  • Patent number: 10810398
    Abstract: Provided are a display panel and a display device. The display panel includes a display assembly, which includes a base substrate and a plurality of light-emitting units disposed on one side of the base substrate, where each of the plurality of light-emitting unit includes a reflective electrode; a fingerprint recognition assembly, which is disposed on one side of the reflective electrode facing away from a light emitting surface of the light-emitting unit, and includes at least one fingerprint recognition unit which is configured to perform fingerprint recognition; and a first reflecting layer, which is disposed on one side of the reflective electrode facing to the fingerprint recognition assembly and includes at least one first reflecting unit, where at least part of a vertical projection of the first reflecting unit on a film layer where the fingerprint recognition unit is located is in an area other than the fingerprint recognition unit.
